Enabling the clearest contrast effect for pattern recognition of the iris, the NIR-C19M series from EVERLIGHT Electronics offers a precise and quick process with very strong heat dissipation.

Following the market demand and the resulting development of appropriate high technology, the concept of ‘body is access code’ has been integrated into many systems and devices. Smart biometric identification allows measuring the users’ unique patterns in the fingerprint, voice, iris and face quickly and easily to avoid the problem of recalling long passwords.

Infrared LEDs for non-contact optical identification have the advantages of compact size, strong security and quick recognition speed which make them an increasingly sought-after advanced technology around the world.

EVERLIGHT’s NIR-C19M series for non-contact optical iris recognition adopts a moulding manufacturing process. Compared to the traditional glue dispense manufacturing process, moulding results in a smoother surface which not only enhances the look but also increases reliability.

The NIR-C19M series works with a wavelength of 810nm and uses an advanced ISP image processor together with CMOS sensor; this is to receive the infrared reflection by the human eye and to authenticate iris identification. Its unique optical design achieves a clear high reflection rate, a small angle (FOV=25) and a radiant intensity of up to 2,700mW/Sr below/less than 1000mA. The heat dissipation with a thermal resistance of 4.38?/W is yet to be matched by any other competing product in the market.

The device has passed IEC62471, a safety regulation to prove that no harm arises to human eyes and skin. In addition to these optical features, the dimension of NIR-C19M series is merely 3.5 x 3.5 x 2.3 mm, which is particularly desirable for space-constrained portable devices.
